Run the unit tests, and everything should pass. At this point, you should be feeling
a bit of paranoia. Maybe these tests are broken and they
always
pass? It's time to
do some test-driven development and get the buzz that comes from turning red
tests to green!
Note:
Test-Driven Development (TDD) is a way of developing an application
by writing a test first, then incrementally implementing the feature until the
test passes. The code is then refactored for the next feature or improvement.
TDD methodology goes way beyond the scope of this chapter but may be
something you'll find useful. The steps you're covering here will help you use
TDD if you do decide to follow it.
Add the following methods to
CampSiteServiceTests.swift
to test
getCampSite()
:
func
testGetCampSiteWithMatchingSiteNumber() {
campSiteService.addCampSite(
1
, electricity:
true
,
water:
true
)
let
campSite = campSiteService.getCampSite(
1
)
XCTAssertNotNil(campSite,
"A campsite should be returned"
)
}
func
testGetCampSiteNoMatchingSiteNumber() {
campSiteService
.
addCampSite
(
1
, electricity:
true
,
water:
true
)
let
campSite =
campSiteService
.
getCampSite
(
2
)
XCTAssertNil
(campSite,
"No campsite should be returned"
)
}
